Using TB in Windows 10. This has been happening for a couple of versions of TB, Lightning, and Provider. I choose "New Calendar" and subscribe to the particular Google calendar that I want to add, then click Next. I can see the events briefly show up in the monthly calendar pane, but they almost immediately disappear. I can still see them stack up in the "All Events" pane, until I click "Finish." Then all the events in the "All Events" pane also disappear, and I'm left with no events in my calendar. No amount of syncing, unsubscribing and resubscribing, or uninstalling and reinstalling Lightning and/or Provider seems to fix this.

I am happy to provide whatever information anyone might need to help me with this.
